Barry and Ralph train to defeat Devo, and Barry becomes annoyed by Ralph's apparent inability to be serious. The team manages to find Janet Petty. When Barry and Ralph confront her, it is revealed that Petty can manipulate a person's gravitational pull, which she demonstrates on Barry. Fearing once again that Ralph is not taking things seriously, Barry refuses to work with him. Ralph reveals that his comedic attitude stems from a difficult childhood when his father abandoned him, forcing him to make jokes whenever he is scared or under pressure. Barry relents, and they go to stop Janet at the gala. Janet uses her powers on Barry, causing him to float in the atmosphere. Barry tells the team to trust Ralph to improvise. Ralph detains Janet and then becomes a giant airbag to allow Barry to land safely. Devoe's wife discovers that he drugged her, but he erases her memory of it, which is revealed to have happened several times, so that she can continue to help him. Breecher comes to Earth-1 to ask Cisco for help, as some of his powers have failed. Harry takes the thinking cap to Thawne's time vault to recharge it, and activates Gideon.
